I downloaded the latest version of Kendo UI (Version: 2020.1.406) for MVC and upgraded my project to refer the latest JS, CSS and Kendo.MVC (2020.1.406.545).

NoRecords method is behaving differently in the latest version. While fetching records in progress, it displays the 'No record found' message even before completion of the action method. Please see the below image:

It was not happening in the version 2018.2.516, it was showing the 'No record found' message after completion of the action method and only if there is 0 row returned.

Below is the code of Student.cshtml view:

Not sure if this is already in the works but when building mvc grids it would be helpful to have the ability to prevent a column from getting too big when the screen size is larger than the grid needs. Right now if columns are turned off and there is more space for the unlocked columns, they expand to fill the page which is normally fine but in some instances it looks silly to have a column for example that you would enter a 2 digit number in to be 300 plus px wide.

https://demos.telerik.com/aspnet-mvc/grid/foreignkeycolumn

In addition to the Foreign Key editor template, populate a list which holds all the categories and pass it via the ViewData - you can see how this is done in the ForeignKeyColumnController.cs PopulateCategories() method.

On the above page, the above statement is made.  Other than the function call to PopulateCategories() I don't ever see the actual code run in the function shown anywhere.  Can someone please add that code and/or point me to my misunderstanding?

Thank you.

Bug report

Reproduction of the problem

1. Set up a Grid to use server binding
2. Add a custom command:

columns.Command(command => command.Custom("View Email"))
	.Title("Body")
	.Width(150);

Current behavior

When the Grid is configured to use server binding, it will render an anchor element. If remote binding is used, the Grid will correctly render a button element.

Expected/desired behavior

Consistency in the rendering. A button element should be rendered, regardless of using server or remote binding.

Environment

• Kendo UI version: 2022.3.913
• jQuery version: x.y
• Browser: [all]

Bug report

Exemplary configuration:

@(Html.Kendo().Grid<MyApp.Models.SampleTable>()
	.Name("grid")
	.ColumnMenu()
	.Scrollable(s => s.Enabled(true).Height("auto"))
	.DataSource(dataSource => dataSource
		.Ajax()
		.Model(model => model.Id(p => p.PrimaryKey))
		.Read(read => read.Action("Read", "Home")) 
		.Sort(sort => sort.Add("ColumnDate").Descending())
	)
	.Resizable(resize => resize.Columns(true))
	.Columns(columns =>
	{
		columns.Select().Width(60);
		columns.Group(group => group
			.HeaderTemplate(@<text><a class='k-link myHeaderTemplate' href=''>@ViewBag.MyHeaderTitle</a></text>)
			.Columns(c =>
			{
				c.Bound(x => x.Field1).Width("10%");

			})
    );
		columns.Bound(c => c.Field3)

		columns.Bound(c => c.Field4);
		columns.Bound(c => c.Field5).Hidden(true).Format("{0:dd-MM-yyyy hh:mm:ss tt}").Filterable(f => f.UI("dateFilter").Cell(cell=>cell.ShowOperators(false)));
		columns.Bound(c => c.Field5).HtmlAttributes(new {style="text-align:right" })
			.Filterable(f=> f.Cell(c=>c.Template("intFilter")))
			.HeaderHtmlAttributes(new { style="text-align:right" });
		columns.Bound(c => c.Field6).Filterable( f=>f.Cell(cell=>cell.ShowOperators(false).Operator("contains")));
		columns.Bound(c => c.Field7);
		columns.Bound(c => c.Field8);
	})
	.Filterable(ftb => ftb.Mode(GridFilterMode.Row))
	.PersistSelection()
    .Pageable(pager => pager
        .PageSizes(new int[] { 10, 20, 30 })
    ) 
    .Sortable()
    .Filterable()
    .Editable(e => e.Mode(GridEditMode.PopUp).DisplayDeleteConfirmation(false))
    .Excel(excel => excel
        .FileName("Export.xlsx")
        .Filterable(true)
        .ProxyURL(Url.Action("Excel_Export_Save", "Grid"))
    )
)

For a sample project, contact Ivan Danchev or Georgi Yankov.

Reproduction of the problem

If one of the columns (e.g. Field6) has a long header title calling the autoFitColumn and passing the column to it does not properly resize the column. The column remains narrow and its header text remains cut off.

Similarly, the method does not have the expected effect on columns with shorter text in the header, i.e. they remain wide instead of shrinking to the text length.

Current behavior

Incorrect column resizing.

Expected/desired behavior

Correct column resizing.

Environment

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/InUYAheR/4
Drag and drop a row from Grid2 to Grid1 by following the steps below:

1. Click and hold down the mouse button within a Grid2 row, just before its ID value or a little after it.
2. Drag the row to Grid1 and drop it over row 3 or row 4.

Current behavior

Grid1's first row values get updated, instead of the drop target row values. This is because e.target in the DropTarget's "drop" event does not return the actual target you drop over.
If you click and drag in the middle of the Grid2 row, drag it and drop it over a row in Grid1, the drag and drop functionality works as expected: e.target returns the correct target.

Expected/desired behavior

e.target should consistently return the target you drop over, regardless of where in the dragged row you have clicked.

Bug Report

When the grid is bound to an external dataSource, the AutoBind(false) setting is not serialized and as a result, the grid binds immediately

Reproduction

• Take the basic usage grid demo https://demos.telerik.com/aspnet-mvc/grid/basic-usage
• Extract the data source and set it to the grid
• set AutoBind(false)

    @(Html.Kendo().DataSource<Kendo.Mvc.Examples.Models.CustomerViewModel>()
    .Name("myDs")
    .Ajax(r=>r.Read(a=>a.Action("Customers_Read", "Grid")))
    )
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.CustomerViewModel>()
        .Name("grid")
        .AutoBind(false)
        .DataSource("myDs")
        /* other settings */
    )

Current Behavior

Expected Behavior

The grid should not bind initially.

When using the Grid Endless Scrolling, is there a way to prevent the existing records from momentarily disappearing as the spinner appears?

Using endless scrolling on a large grid (full screen), the users eye tracks down the list as the mousewheel is turned. At the moment the next page is fetched, the view of the data is disrupted as the spinner appears and the data disappears. This can be quite jarring to the senses when browsing for a specific record in the list.

On a small grid such as that on the example page (https://demos.telerik.com/kendo-ui/grid/endless-scrolling-remote) it isn't quite as jarring on the senses, but with a large grid with many columns and rows, it can be very off-putting.

Ideally, if the existing records can remain opaquely visible in the background under the spinner whilst the next page of data is being retrieved, it would produce a much cleaner user experience.

Describe the bug
Column headers do not resize properly in IE11 when scrollable is set to false. Regression introduced in 2021.3.914.

To reproduce
Steps to reproduce the behavior:

1. Go to https://demos.telerik.com/kendo-ui/grid/selection-export?autoRun=true&theme=bootstrap-main

The column headers are squished to the left side.

Expected behavior
Columns headers must have the same width as the respective columns.

Workaround:

.k-ie .k-grid-header {
  display: table-header-group;
}

there seems to be a bug in your commands column and it's made worse when loading/saving grid layouts.

When i load a page with this grid column definition, 

.Groupable()
                    .Columns(columns =>
                    {
                        columns.Command(cmd => cmd.Custom("Undelete")
                            .Click("undelete"))
                            .Width(60);

when you inspect the grid, the grid internally shows two classes for the command cell:

attributes: {class: 'k-command-cell k-command-cell'}

now, if i apply a grid layout, the problem gets worse.  This sample code will cause the dom to end up with multiple k-command-cell classes on the grid's td element.

$("#UndeleteGrid").data("kendoGrid").setOptions($("#UndeleteGrid").data("kendoGrid").getOptions())

<td class="k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell" role="gridcell"><a role="button" class="k-button k-grid-Undelete" href="#" title="Undelete"><span class="k-icon k-i-undo"></span></a></td>

We set up a grid that auto-filters a name field to "does not contain" and the value it excludes is "[DEACTIVATED]".  This column is also filtering out records that have a null in them if this filter is set.  I had to change the datasource to return an empty string instead.
